QW800-K seriesSales of two position two-way sanitary clamp pneumatic ball valveIt is a valve specifically designed for hygiene grade fluid control. It adopts a clamp type connection method, which is suitable for the hygiene requirements of industries such as food, pharmaceuticals, and beverages. Here is its working mechanism:

1. Structural composition: The QW800-K series two position two-way sanitary clamp pneumatic ball valve consists of a valve body, a ball body, a valve stem, a seal, and a pneumatic actuator. There are two channels inside the valve body, and the sphere is located in the channels to control the flow of fluid through rotation.

2. Working state: When no pneumatic signal is applied, the pneumatic actuator is in a neutral state, the ball is pushed towards the valve seat by the valve stem, the valve is in a closed state, and fluid cannot pass through. When a pneumatic signal is applied, the pneumatic actuator works to change the position of the sphere and achieve the opening or closing of the valve.

3. Opening process: When the pneumatic actuator receives the opening signal, the pneumatic piston pushes the valve stem upward, causing the ball to leave the valve seat and open a channel for fluid to pass through. At this point, another channel is connected to the sphere, and fluid flow is unobstructed.

4. Closing process: When the pneumatic actuator receives a closing signal, the pneumatic piston pushes the valve stem downward, causing the ball to come into contact with the valve seat again, closing the opened channel and preventing fluid from passing through.

5. Sanitary design: The QW800-K series two position two-way sanitary clamp pneumatic ball valve meets sanitary requirements. The valve body and ball body are made of stainless steel material, with a smooth and easy to clean surface to prevent bacterial growth. The sealing components are made of food grade silicone or polytetrafluoroethylene (PTFE) materials, which have good corrosion resistance and sealing performance.

It should be noted that the specific working mechanism may vary depending on different models and manufacturers. Before using the QW800-K series two position two-way sanitary clamp pneumatic ball valve, it is recommended to refer to the product manual or consult the manufacturer to understand the specific working mechanism and operating points.
